Jointly promoting green agricultural development, I will send you seeds... Shanghai and Yunnan agricultural technicians exchange "family background", you will send me insect technology | agriculture | family background
"Insects from Yunnan are flying, our seeds are passing. Friends come and go." Recently, in the glass greenhouse of Shanghai Jiufeng Agricultural Expo Park located in Fengjing Town, agricultural officials from Ning'er County, Pu'er City, Yunnan Province and Jinshan jointly released a batch of special small insects, initiating a new attempt to improve the level of green agricultural production through biological control technology.
Prior to this, the seeds of Jinshan had already borne fruit on the land of Yunnan. In March 2022, Hu Xufeng, an agricultural technician from Fengjing Town in Jinshan District, joined the Jinshan District Agricultural Technology Talent Assistance Yunnan Project, thus forming an alliance with Ning'er County. Through in-depth and meticulous research, he respectively connected with Shanghai Jiufeng Agricultural Expo Park and Ning'er County Wanli Agricultural Development Co., Ltd., building a platform for agricultural technology exchange between the two places. At the same time, he also carefully selected six new varieties of chili fruits to explore. Through careful comparison, Ning'er County selected four varieties with good taste and strong disease resistance.
In May of this year, Hu Xufeng, who was about to end his aid trip to Yunnan and return to Shanghai, began searching for a "gift" from Ning'er County to Jinshan District under the leadership of Gong Liang, the deputy county magistrate of Ning'er County. Finally, he finalized the "four pests and one dose" products produced by Fengshuo Agriculture Co., Ltd. in Ning'er County, Pu'er City, including aphid cocoon bees, armyworm black egg bees, predatory mites, pronged stink bugs, and tobacco endogenous antiviral preparations. "Aphid cocoon bees will lay their eggs inside the aphids, and the larvae 'hatching and development will consume the nutrients inside the aphids and become stiff aphids. Then, under suitable temperature conditions, they will emerge as adults, achieving the goal of using insects to control pests."

"How long do aphid cocoons survive in the field? How to control the population size of beneficial insects, and how to build a 'breeding insect' industry chain locally?" At a symposium between agricultural technicians in the two regions, agricultural technicians in Jinshan District, who were extremely interested in this technology, raised a series of questions.
Due to the significant differences in temperature, sunshine and other conditions between Yunnan and Shanghai, whether the insects in Yunnan are suitable for the climate of Shanghai has become an urgent issue that needs to be addressed. So, both sides decided to search for a suitable piece of land in Shanghai for joint research. This task has landed at Shanghai Jiufeng Agricultural Expo Park, which has the largest single modern glass greenhouse in Asia.
"This batch of insecticides covers approximately 50 acres of farmland. In a closed glass greenhouse, it is easier to create an ecological environment suitable for beneficial insect reproduction and maintain population stability," Hu Xufeng explained.

At the scene of the release of aphids and cocoons, Li Biao, a senior engineer from Sannong Company, observed the yellow sticky insect boards arranged in the field and excitedly said, "We once invested 8 million yuan to create a genetic map of aphids and cocoons. From the small number of aphids and cocoons discovered in Jiufeng, it can be preliminarily judged that this belongs to the same variety as the one we brought, indicating that Yunnan aphids and cocoons can adapt to the local environment."
On the day of the event, Shanghai Fengjing Jiufeng Agricultural Technology Co., Ltd. and Ning'er Fengshuo Agricultural Development Co., Ltd. signed a strategic cooperation framework agreement. Shanghai Jiufeng will provide technical output in the fields of agricultural development concepts, production capacity configuration optimization plans, etc. with its own agricultural seed products and specific agricultural product planting technologies. Ning'er Fengshuo will cooperate with Jiufeng as the main exchange project on "pest control" technology to promote the upgrading of regional agricultural technology levels between the two sides. Next, Jiufeng will select suitable tomatoes for planting and conduct a trial planting in Ning'er.
Zhai Xin, Deputy Director of the Agriculture and Rural Committee of Jinshan District, said, "Currently, Jinshan District is applying for a national green production pilot zone, and green prevention and control, as well as pest control technology, are areas of great concern to Jinshan. The cooperation between Ning'er and Jinshan in agricultural products has a long history, and the agricultural technology exchange initiated in recent years has broad prospects. Different lands can experiment with the potential of various new agricultural products, and jointly produce new agricultural technology achievements."
